4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Steven Rostedt <rost...@goodmis.org>

commit 37815bf866ab6722a47550f8d25ad3f1a16a680c upstream.

The module notifier call chain for MODULE_STATE_COMING was moved up before
the parsing of args, into the complete_formation() call. But if the module 
failed
to load after that, the notifier call chain for MODULE_STATE_GOING was
never called and that prevented the users of those call chains from
cleaning up anything that was allocated.

Fixes: 4982223e51e8 "module: set nx before marking module MODULE_STATE_COMING"
